Part 2: Explanations / Functions
Explanation of the set values
Heat slope: Relationship between outside temperature
and flow temperature (for floor heating approx. 0.6) =>
(only with outdoor sensor connected [Terminals 5+6])
Note on setting:
In the case of cold outside temperatures and too low room
temperature => Increase heat slope
In the case of high outside temperatures (e.g. 16°C / 61°F)
and too low room temperature => Correction via the set
room temperature value
The following graph provides a guideline to setting the heat
slope.

Outside temperature
Heat slope adaptation: ON/OFF
Function for automatic adjustment of the heat slope =>
(only with outdoor sensor connected [Terminals 5+6])
The adaptation is only activated at outside temperatures
below 8 °C /46°F when the room temperature is below
18 °C / 64°F.
During the adaptation, warm-up of the living room begins
after 3 hours at reduced operation (nighttime). Room
temperature regulation is performed with a set value of
21 °C / 70°F. As soon as the room temperature exceeds
20 °C / 68°F, the room is regulated a further ½ hour at
20 °C / 68°F. The flow and outside temperatures are then
measured. The optimum gradient is determined from these
values and is then assumed in the regulation.
The calculation is made once
following activation. The
smallest possible heat slope for radiator heating is set to
"1
". Large surface heating (floors, walls, ceiling, ...) should
have heat slopes less than "1".
If the required room temperature has not been reached
during 4 hours of the adaptation, it is canceled (warning
indicator flashes). If the adaptation is canceled, it is
repeated on the next day.
Hot water preparation is blocked during the adapting.
